Life maintenance apparatus

ABSTRACT

A kind of life maintenance apparatus to be used in case of earthquake or other disasters when users are buried in debris of collapsed building. The six sides box-type bed includes two parallel upper and bottom layers of high strength material made plates, two covering plates at front and back, and two adjustable plates on both sides. Beneath the upper layer, there are certain chambers of storage for life maintenance stocks and oxygen reproducer and one wireless signal transmitter. On the bottom layer, there is a rubber cushion layer on top of which fixed with manul instant inflating air cushion, together with safety-belt. Thanks to the high anti-impact material shell of the apparatus, it&#39;s signaling apparatus and life-maintenance stocks, it could well provide its inhabitants in case of need, sufficient protection from strike, material for life maintaining for over 20 days. It exists in your bedroom as a normal bed.

[0001] This utility model relates to a kind of life maintenance apparatus, and more particularly relates to a kind of life maintenance apparatus, which is being used while earthquake is occurring.

[0002] As one of the most powerful natural disasters, earthquake has always been our nightmare since ancient times. With the development of modem science and technology, peoples have made significant progress in seismic forecast and anti-seismic buildings, however, owing to it's difficult to be predicted, earthquake still hurt thousands of lives around world every year, Sudden unexpected strong earthquake at night remains lifetime nightmare terror for those who experienced or survived from such kind of situation.

[0003] Peoples are very fragile to the strike from the collapsing buildings or even a small part of it and as a result of it then died from the first strike of such collapse. Among them even some could survive, but being hurt and buried deeply underneath the ruins, waiting desperately for rescue. However, rescuers often come too late owing to low efficiency in locating survivors and avoiding using machines. Survivors over one week, by their own confidence to live on and with great luck to be found by rescuers, are so rare that normally they are regarded as miracles.

[0004] The purpose of this utility model is to provide a kind of life maintenance apparatus which can be applied by the people who involved in the earthquake to rescue themselves.

[0005] The Life Maintenance Apparatus (LMU) according to this utility model is six sides shell of high strength material, composed of two parallel horizontal rectangular plates, bolstered with five to nine round stands. Fixed on it's front and back, there are two vertical covering plates. On two sides, there are two adjustable plates which in normal time, folded inside to beneath the upper layer.

[0006] On the bottom layer, it is covered with one extra layer of cushion material like rubber, on top of which there is another manual instant inflating air cushion in shape of L whose extra bulge part gives extra protection of head. Safety belt(s) combined with two handles fixed beneath the upper layer to protect user from rolling are installed in proper position as well.

[0007] Beneath the upper layer, it is installed with one wireless signal transmitter operated by battery and can send the fixed frequency signal. Surrounding the transmitter, there are several chambers of chemicals, that when unsealed could start as oxygen re-producer, by consuming carbon-dioxide. In the rest part beneath the upper layer, it is installed with several storage chambers for life maintenance materials, essentially water, and others like medicine, battery, food, mobile phone, radio etc. Opposite to the air cushion, there are 2 fixed handles.

[0008] The two folding side-plates could be pulled down in case of need, to form a complete six sides shelter.

[0009] The six sides structure of this apparatus, made from high strength material, could significantly reduce the impact from collapsing building to protect it's user from being killed or hurt. When the user is buried inside the debris, he can installed the battery to the wireless signal transmitter to send it's position to the its receiver (such as rescuer) so that the latter could spot the user's accurate position rapidly With the stocked material and oxygen reproducer, the user could easily keep alive for twenty days or more subject to the quantity of stock, even at suffocating surroundings.

[0010] The help to users are both physical and psychological, as the user knows that his chance to be found are quite large, or if he could use one sort of two-way communication, the confidence to survive increases too. Storage chambers could be filled with some basic material like water and other alternatives in user's option. They could be whatever they think maybe necessary in case of trap, like medicine, compact food, blanket, mobile phone, radio, or even chess or poker card, while waiting to be rescued. Because of the shelter, rescuers, when locating the accurate position of the user, could use machinery facilities to speed up the digging process.

[0011] It is ideal to be a form of bed as in sudden strong night earthquake, under bed is probably the only possible distance they are able to reach, in enough short time.

[0012] Below is the further explanation of the fulfillment of this utility model in connection with the corresponding figures

PREFERRED EMBODIMENT

[0021] As illustrated in FIG. 1, the LMU's upper plate is made by 4 cm thick good quality steel, and the bottom layer plate 8 is made by 2 cm thick steel. They are connected with nine solid steel bolsters 3 with diameter of 7 cm. The front and back covering plates are made by 2 cm thick steel, and two sides are inside-folding plates connecting to the edge of upper plates. On the bottom plate 8, there is a rubber cushion 7 of 2 cm thick. On top of rubber cushion, there is an L-shape air-cushion 5, using manual instant inflating, as that sort of lifejacket used on plane, and among air-cushion is the safety belt to fix the user. Opposite the air-cushion on beneath top plate, it is balance maintaining handle 4. 9 is the wireless signal transmitter, 11 is the oxygen reproducer chamber and on back side, are chambers of storage.

[0022] Considering the overweight of steel, other high strength combination materials, like ABS engineering plastics, glass steel, carbon fiber or other light weight, low cost materials could also be considered.

[0023] The apparatus is designed for earthquake, but it's principle of protection and life maintenance could also be applied to other similar circumstances caused by other disasters: tornado, war. And if the material could be heat-isolating, it could even be used incase of fire, volcano eruption.
